Noticeable Bump At 7 Weeks Baby #3

Hey girls is it normal to show early with a third pregnancy? I'm 7 weeks and I'm growing a bump already? Since 4 weeks I've noticed it but I passed off as bloating Ect but, it's never gone down from the moment I wake up to the moment I go to sleep is there. It's hard too? And stays there even when I lay down. I normally have a flat tummy too I'm a size but I can't even fit in my clothes. I keep putting off buying maternity clothes and I'm living in track suit bottoms lol but I'm starting to think it is a baby bump not just bloating .. Or is it twins What u think ladies oh and ps no chance if being further than I thought according to last period I'm 7ish weeks xx

I showed earlier with each pregnancy, I think I was about 6 wks with my 3rd when I realised I was pregnant and wasn't showing then. My 4th however I had a bump at 6 wks that just kept on growing and didn't go down. That was twins. It's always hard to tell because we all carry differently and change at different rates, you are very slim to start with so who knows.
